If I had mod points, I would mod the parent up. I have taught for 28 years and was Novell/Microsoft certified in the 90's. I have installed and administered various Linux servers over the years because they just worked and I could repurpose hardware easily on a budget.

I currently administer a Moodle server and due to politics, it is a MS server. For my money, we should be using Linux in the server room, and FOSS software on the desktop where possible. As the parent said, software lockin is huge, and culture is hard to change.
